Technical Field

[0001] The utility model relates to the technical field of building engineering supports, in particular to a building engineering support with an adjustable structure. Background Art

[0002] In the construction work of a building project, the working height will increase as the building rises. Therefore, for construction work at higher positions of the building, workers usually need to use a bracket to assist the work. In order to adapt to the work of people of different heights and construction work requirements at different heights, a construction engineering bracket with an adjustable structure is needed.

[0003] According to a publicly disclosed construction engineering support (publication number: CN220226151U), in the above application, the transmission sprocket drives the other three transmission sprockets through the chain to start rotating synchronously, the four transmission sprockets respectively drive the four threaded rods to start rotating synchronously, the four threaded rods drive the lifting surface to start moving upward, and the lifting surface drives the workers to move upward.

[0004] However, during the actual use of the above-mentioned equipment, the center of gravity of the bracket will also rise when the bracket is raised, and the risk of shaking or overturning is more likely to occur when personnel are working on the bracket, thereby reducing the operating safety of the staff when using it; in view of this, we propose a construction engineering bracket with an adjustable structure. Utility Model Content

[0005] The purpose of the utility model is to provide a building engineering support with an adjustable structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a construction engineering support with an adjustable structure, comprising a base, the upper surface of the base is fixedly connected to the bottom end of a hydraulic rod, the top end of the hydraulic rod is fixedly connected to a top plate, the upper surface of the base is provided with an auxiliary positioning mechanism, and the auxiliary positioning mechanism comprises:

[0009] Preferably, the number of the hydraulic rods is four, and the four groups of hydraulic rods are distributed in a rectangular array at the four corners of the upper surface of the base, and the electric push rod is arranged at the center of the base, so that the top plate can obtain a stable bottom support effect.

[0010] Preferably, the end of the transmission plate is arranged in a T shape, and a T-shaped groove adapted to the transmission plate is opened on the bottom inner wall of the disc, and the transmission plate is arranged in the T-shaped groove, so that the transmission plate can stably move horizontally on the inner wall of the disc.

[0011] Preferably, a circular cavity is formed on the inner wall of the top plate, and the round rod and the contact wheel are arranged inside the circular cavity.

[0012] Preferably, the size of the rubber airbag is matched with that of the ridge, so that the ridge on the arc-shaped outer wall of the contact wheel and the rubber airbag on the arc-shaped outer wall of the disc are in a state of mutual engagement.

[0015] Compared with the prior art, the utility model provides a building engineering support with an adjustable structure, which has the following beneficial effects:

[0016] 1. The building engineering support with an adjustable structure is provided with an auxiliary positioning mechanism. When the center of gravity rises due to the height adjustment of the support, the electric push rod is controlled to retract, so as to cause the circular plate to produce a downward pulling force on the connecting rod, thereby causing the transmission plate to drive the disc to maintain the downward pulling force. When the top plate shakes, a relative displacement occurs between the disc and the top plate. Through the setting of the volute spring, several groups of contact wheels arranged in a circular array in the circular cavity can effectively suppress the relative rotation that may occur between the top plate and the disc, thereby causing the top plate to quickly stop, so as to ensure the overall stability and safety of the equipment.

[0017] 2. The construction engineering support with an adjustable structure is provided with a transmission gear inside the T-slot that can transmit the transmission plate and the arc-shaped push plate. When the transmission plate is subjected to a downward pulling force to generate a sliding force, the arc-shaped push plate cooperates with the transmission gear to compress the compression airbag, so as to keep the rubber airbag in an expanded state, so as to maintain a more stable gripping effect on the contact wheel, and further ensure the stability of the top plate after the height is raised.

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a construction engineering support with an adjustable structure, including a base 1, the upper surface of the base 1 is fixedly connected to the bottom end of a hydraulic rod 2, the top of the hydraulic rod 2 is fixedly connected to a top plate 3, and the upper surface of the base 1 is provided with an auxiliary positioning mechanism, the auxiliary positioning mechanism includes an electric push rod 4, a circular plate 5, a connecting rod 6, a transmission plate 7, a circular disc 8, a round rod 9, a contact wheel 10, a volute spring 12, a convex ridge 11 and a rubber airbag 13.

[0026] In one embodiment of the utility model, an electric push rod 4 is fixedly mounted on the upper surface of the base 1, a circular plate 5 is fixedly mounted on the top of the electric push rod 4, the bottom end of a connecting rod 6 is hinged to the inner wall of the circular plate 5, a transmission plate 7 is hinged to the top of the connecting rod 6, a disc 8 is rotatably mounted on the inner wall of the bottom of the top plate 3, a round rod 9 is rotatably mounted on the inner wall of the top plate 3, a contact wheel 10 passes through the round rod 9, and the contact wheel 10 is fixedly connected to the round rod 9, a volute spring 12 is sleeved on the arc-shaped outer wall of the round rod 9, a convex ridge 11 is opened on the arc-shaped outer wall of the contact wheel 10, and a rubber airbag 13 is arranged on the arc-shaped outer wall of the disc 8.

[0027] Furthermore, the number of hydraulic rods 2 is set to four groups, and the four groups of hydraulic rods 2 are distributed in a rectangular array at the four corners of the upper surface of the base 1, so that the top plate 3 can obtain a stable support effect at the bottom, and the staff can control the extension and shortening of the hydraulic rods 2 according to actual use requirements, so as to adjust the height of the top plate 3. In addition, the electric push rod 4 is arranged at the center of the base 1, and the number of connecting rods 6 is set to three groups, and the three groups of connecting rods 6 are evenly distributed on the arc-shaped outer wall of the circular plate 5 in a circular array, so that the circular plate 5 can adjust the height of the top plate 3 at the top. The transmission of the disc 8 in the plate 3 is more stable. Specifically, the end of the transmission plate 7 is arranged in a T shape, and a T-shaped groove compatible with the transmission plate 7 is opened on the bottom inner wall of the disc 8. The transmission plate 7 is arranged in the T-shaped groove, so that the transmission plate 7 can stably move in the horizontal direction on the inner wall of the disc 8. Specifically, after adjusting the height of the top plate 3, by controlling the electric push rod 4 to retract downward, the circular plate 5 and the connecting rod 6 are cooperated to generate a downward pulling force on the transmission plate 7 and the disc 8, thereby prompting the disc 8 and the top plate 3 to maintain a relatively stable state.

[0028] In addition, a circular cavity is opened on the inner wall of the top plate 3, and the round rod 9 and the contact wheel 10 are arranged inside the circular cavity. At the same time, the number of contact wheels 10 is arranged in several groups, and the several groups of contact wheels 10 are evenly distributed on the arc-shaped outer wall of the disc 8 in a circular array, and the arc-shaped outer surface of the contact wheel 10 is tightly attached to the arc-shaped outer wall of the disc 8. Specifically, the two ends of the spiral spring 12 are respectively fixedly connected to the inner wall of the circular cavity and the arc-shaped outer wall of the round rod 9, so that when the contact wheel 10 is affected by the rotation of the disc 8 and rotates, the elastic force of the spiral spring 12 prompts the round rod 9 to drive the contact wheel 10 to maintain a movement trend of reverse rotation, thereby suppressing the rotation of the disc 8. In addition, the rubber airbag 13 is adapted to the size of the convex rib 11, so that the convex rib 11 on the arc-shaped outer wall of the contact wheel 10 and the rubber airbag 13 on the arc-shaped outer wall of the disc 8 are in a state of mutual engagement.

[0029] In an embodiment of the utility model, a transmission gear 14 is rotatably installed on the inner wall of the T-shaped slide groove, and a tooth pattern that can mesh with the transmission gear 14 is provided on the upper surface of the transmission plate 7. A transmission cavity is opened on the top of the disc 8, and an arc-shaped push plate 15 is slidably installed on the inner wall of the transmission cavity, and a compression air bag 16 is fixedly installed on the inner wall of the transmission cavity.

[0030] Specifically, the compressed airbag 16 is arranged in a circular ring shape, and the compressed airbag 16 is connected with the rubber airbag 13. In addition, the outer surface of the arc-shaped push plate 15 is adapted to the inner surface of the compressed airbag 16, and a plurality of metal plates are arranged on the outer wall of one side of the arc-shaped inner surface of the compressed airbag 16 to suppress the tendency of the compressed airbag 16 to deform toward the center of the disk 8, so that the compressed airbag 16 will exhaust toward the rubber airbag 13 when squeezed. Specifically, the interior of the compressed airbag 16 and the rubber airbag 13 is filled with inert gas to ensure the stability of the compressed airbag 16 and the rubber airbag 13 during use.

[0031] In the utility model, when in use, the hydraulic rods 2 are started to control the four groups of hydraulic rods 2 on the base 1 to lift the top plate 3 upward, thereby controlling the height of the equipment body to achieve the adjustment effect and facilitate the use of construction personnel. At the same time, an auxiliary positioning mechanism is provided, when the center of gravity rises due to the height adjustment of the bracket, the electric push rod 4 is controlled to contract to prompt the circular plate 5 to produce a downward pulling force on the connecting rod 6, thereby causing the transmission plate 7 to drive the disc 8 to maintain a downward pulling force. When the top plate 3 shakes, a relative displacement occurs between the disc 8 and the top plate 3. Through the setting of the volute spring 12, the several groups of contact wheels 10 arranged in a circular array in the circular cavity can effectively suppress the relative rotation that may occur between the top plate 3 and the disc 8, thereby prompting the top plate 3 to quickly stop, so as to ensure the overall stability and safety of the equipment.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
